Cosecant | Definition, Formulas, & Facts | Britannica
Mar 31, 2025 · cosecant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is csc A = length of hypotenuse/ length of side opposite angle A. (The other five trigonometric functions are sine [sin], cosine [cos], tangent [tan], secant [sec], and cotangent [cot]. Cosecant is also abbreviated as cosec.)
Cosecant - Math Open Reference
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'. Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.
Trigonometric Identities - Math is Fun
When we divide Sine by Cosine we get: So we can say: That is our first Trigonometric Identity. We can also divide "the other way around" (such as Adjacent/Opposite instead of Opposite/Adjacent) to get: Cosecant Function: csc (θ) = Hypotenuse / Opposite. Secant Function: sec (θ) = Hypotenuse / Adjacent.

Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

csc,sec与sin,cos,tan的关系 - 百度知道
csc(余割)和sec(正割)是三角函数中与sin(正弦)和cos(余弦)函数的倒数。 它们之间的关系是csc (x) = 1/sin (x),sec (x) = 1/cos (x)。
